$\frac{\tan\left(0\right)-\tan\left(0\right)^3}{\cos\left(0\right)}$
Learn how to solve differential calculus problems step by step online. Find the limit (x)->(0)lim((tan(x)-tan(x)^3)/cos(x)). Evaluate the limit \lim_{x\to0}\left(\frac{\tan\left(x\right)-\tan\left(x\right)^3}{\cos\left(x\right)}\right) by replacing all occurrences of x by 0. The cosine of 0 equals .
